Start by reproducing the CMake build with PROCDUMP_DISABLE_SYSTEM_LIBBPF=OFF and inspect the procdump_ebpf target that runs /usr/sbin/bpftool gen object on procdump_ebpf.o. Compare the system libbpf and bpftool versions involved; done means the project builds successfully and generates procdump.ebpf.o.
